    • A security system which is suitable for use in a vehicle. The security system is a passive entry and passive re-mobilization system in which a security controller transmits a command signal LCs to a remote transponder, which replies with a LF response signal LRs. If an LF response signal is not received in response to the transmission of a command signal LCs, the security controller re-transmits the command signal, again as an LF command signal LCs. On determining that a command signal is a re-transmitted command signal, the remote transponder re-transmits the response signal as an UHF response signal URs.
    • 适用于车辆的安全系统。 安全系统是被动进入和被动重新动员系统,其中安全控制器向远程应答器发送命令信号LC,远程转发器用LF响应信号LRs进行回复。 如果响应于命令信号LC的发送没有接收到LF响应信号,则安全控制器再次发送命令信号作为LF命令信号LC。 在确定命令信号是重新发送的命令信号时,远程转发器将响应信号重新发送为UHF响应信号UR。

    • A tire pressure monitoring system (12) for a vehicle (10) includes a speed sensor (38) generating a speed signal indicative of vehicle speed, a timer (44) generating a time signal, a warning status memory (26) having warning statuses therein. The system further includes a plurality of rolling tires in respective rolling location. The plurality of rolling tires (14a), (14b), (14c) and (14d) have respective rolling transmitters (16a), (16b), (16c) and (16d). An auxiliary tire (14f) in an auxiliary location has an auxiliary transmitter (16f) that generates an auxiliary sensor transmission signal. A controller (22) is coupled to the rolling transmitters, the spare tire transmitter and the warning status memory (26). The controller (22) receives the auxiliary sensor transmission signal. When the speed is greater than a predetermined speed and, when the time signal is greater than a predetermined time, the controller associates the auxiliary sensor identification to an auxiliary location of the warning status memory.

    • A vehicle security system comprises a transmitter 18 for transmitting coded signals, a receiver 16 for receiving the coded signals, and a control unit 14 for operating an engine immobilization system 12 in response to receipt by the receiver 16 of a valid coded signal. The transmitter 18 is arranged to transmit the coded signal as a sequence of pulses of electromagnetic radiation which are amplitude modulated at a modulating frequency, and the receiver includes an audio frequency filter arranged to pass signals having a frequency within a range including said modulating frequency. This allows the filtering out of high powered interfering signals which are of the same radio frequency as used in the system, but which are not modulated at the same audio frequency.
    • 车辆安全系统包括用于发送编码信号的发射机18,用于接收编码信号的接收机16,以及响应于接收机16接收到有效编码信号而操作发动机固定系统12的控制单元14。 发射机18被布置为将编码信号作为以调制频率进行幅度调制的电磁辐射脉冲序列发送,并且接收机包括音频滤波器,该音频滤波器布置成传递具有包括所述调制频率的范围内的频率的信号。 这允许对与系统中使用的射频相同的高功率干扰信号进行滤波,而不是以相同的音频调制。
